Sadan P. Gowda*, Parthiban S. and Senthilkumar G. P.

ABSTRACT

Microemulsions (MEs) are clear, thermodynamically stable systems. They were used to solubilize drugs and to improve topical drug availability. The formulation of microemulsion for pharmaceutical use requires a thorough understanding of the properties, uses, and limitations of microemulsion. Three distinct microemulsions – oil external, water external and middle phase can be used for drug delivery, depending upon the type of drug delivery upon the type of drug and the site of action. While microemulsions are used in several fields, this article we focuses on the recent development of microemulsion.
